PECOS, N.M. (AP) — A fast-moving fire in New Mexico’s Santa Fe National Forest prompted evacuations of homes and campgrounds, threatened cabins, and closed a state highway Friday.

Officials asked residents in 140 homes — mostly used for the summer — to leave as crews battled the 3.1-square-mile blaze near the communities of Pecos and Tres Lagunas, about 25 miles east of Santa Fe.

They also evacuated campgrounds and closed trailheads around Pecos, Las Vegas and Santa Fe as they worked on containment lines in hopes of preventing the fire from moving toward the capital city’s watershed and the Tres Lagunas community.

Officials said the fire doubled in size by Friday afternoon and was still totally uncontained. That prompted New Mexico Gov. Susana Martinez to declare a state of emergency in San Miguel County to free up state funds to fight the fire.

New Mexico State Forestry spokesman Dan Ware said the evacuations came after the fire jumped state Route 63.

“Fire activity is picking up this morning, and because of expected high winds, low humidity and increasing temperatures, the spread potential is high,” Ware said.

Officials said a downed power line ignited the blaze Thursday. It’s the first major wildfire this year in New Mexico, which is in its driest two-year period in nearly 120 years of record keeping.

“It has been a slow start to the season, until this point,” said State Forester Tony Delfin. “Now we expect the conditions to go on until the monsoons come or the weather changes the pattern.”

Martinez said about 40 people, mostly hikers and campers, have been evacuated from the area.

Meanwhile, firefighters gained ground on a wildfire in the mountains north of Los Angeles. Crews took advantage of cool morning weather to make progress Friday, but scattered flames continued to climb hillsides.

The 2.2-square-mile wildfire was 15 percent contained, and as many as 500 firefighters hoped to make further progress before the day turned hot and dry, U.S. Forest Service spokesman Nathan Judy said.

A flare-up prompted authorities to briefly evacuate about 25 homes along a canyon road in the Angeles National Forest in the morning, but residents were later allowed to return.

“Right now the fire’s not doing a whole lot. It’s just making small runs here and there,” Judy said. “There’s no large fire front.”

He said the blaze was burning near power lines, although utilities reported no damage.

In New Mexico, a helicopter helped with efforts to secure the western perimeter of the fire Friday morning, but it was grounded by late morning due to high winds.

Nearly 300 firefighters were working on the blaze, which was being fueled by winds from the north and northwest.

Duane Archuleta, forest fire management officer for the Santa Fe and Carson national forests, said if winds pushed the blaze toward an area that burned in the 2000 Viveash fire, it might help efforts to contain it.

“The fire could run and hit that ridge and kind of die out on that ridge,” he said.

No structures had burned and no injuries were reported, but the fire was burning near Tres Lagunas, an upscale community of cabins and vacation homes.
